DISK PLOW.

Specification of Letters Patent.

Application led April 10, 1905.

Serial No. 254,691.

Y To all whom it may concern:

-Be it known that I, CLEMENT A. HARDY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-A 1- 1 ful Improvements in Disk Plows, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in disk plows, it relating more-` particularly to the framework which supports the disks.

One of the purposes aimed at is to provide such a construction and relation of parts that greater strength and rigidity shall be attained than those incident to plow frames front disk. This plan of construction has necessitated the presence of a large number of joints, and at these joints are experienced the strains exerted on the plow when at work, the result being that the several parts of the mechanism are subjected to such torsional and displacing stresses that looseness is constantly occurring and breakage of the connecting arts frequently met with.

The object ofp the present construction is to so arrange the frame element that the parts which transmit the main draft shall extend rigidly from the draft devices to the central part of the working area, and have the supplemental working parts arranged symmetrically in relation to this main line of draft or strain.

I form the main central element of the machine in two parts, one at the front for receiving the draft, and the other in rear thereof carrying a plow disk, and the two rigidly secured together, an adjustable connecting device being preferabl employed. These parts of the frame and t e plow disk carried thereby can always remain in workin'g connection whether the implement is to be used as a one disk'plow, or is to be equipped as a two disk plow or a three disk plow. By having a centrally arranged line of draft bars rigidly connected and extending continuously from the draft oint back to the central disk when three dis s are employed the forward disk can have its carrier secured to the central bar and the rear disk can be similarly attached and a much more rigid and durable structure is provided.

Figure 1 is a plan view illustrating a disk plow having parts constructed and arranged to embody my improvements,some of the said parts being shown in full lines and some being conventionally illustrated in dotted lines. Fig. 2 is a plan view showing the parts of the frame used when a single diskplow is to be provided. Fig. 3 is a plan view indicating the construction and arrangement of parts used when three disks are to be employed. Fig. 4 is a plan view of the draft beam or frame to which the central plow frame is rigidly attached. Fig.' 5 is a side view of the parts in Fig. 4. Fig. 6 shows a modification of the connecting devices which join the draft beam and the doubletree.

The central element or main draft element of the plow frame is indicated as an entirety by 1. It can be made in any suitable way. I prefer to form it by properly bending a bar o wrought metal, angle or other, so as to have the conformation, when seen in plan view, that is illustrated in the drawings. v

That is to say, it has the front bar or arm 15, and the central bars 16 and 17, the art at 16 being inclined to the front arm andP extending toward the land and the part 17 being on longitudinal lines. At the rear end it is bent to have the inclined part 18 extending toWa-rd the furrow. It will be understood, however, that the essential features of the invention are not limited to any speciiic form or shape as there can be numerous modifications without departing from the important matters. have selected and above described enable me to attain important ends which will be understood. The forward bar or arm 15 is rigidly secured to the draft beam 4, my low in this respect differing from those in w ich hinge connection has been used or suggested at the point of union between the draft beam and the central plow beam. To the front end of the draft beam 4 are secured in the ordinary way, or in any preferred manner, the draft devices which are provided for hitching the horses. In the construction indicated in the drawings there is a conventional illustration of a four horse hitch comprising swingletrees, doubletrees, etc.

At 6 in Fig. 3 there is indicated a supporting wheel and a set of parts for carryin it and connecting it to the plow frame and to the draft devices. These may be of any well known construction and need not be here described in detail it being sutlicient to say that at 7 T. prefer to have an adjusting apparatus of any of the well known sorts for vertically adjusting the front parts of the framework upon the front wheel. This wheel is inclined to the horizontal and to the vertical and is so situated as to travel along vthe outermost furrow. At 8 there is a second furrow wheel and a set of parts for carrying and supporting it and connecting it to the rear end of the plow frame. The details of this part of .the `structure can also be of any suitable form` The wheel should be mounted at anv inclination to the horizontal and to the ver-tical, and it should be supported in such way that it can move as a caster wheel.

The land wheel indicated by the dotted lines at Q, is connected to thecentral part of the plow frame. This wheel also should have means situated substantially as is indicated by 10 for vertically adjusting the plow frame in relation to it. When the parts requisite to provide a two disk plow are used, as illustrated in Fig. 1 the land wheel and its connecting and adjusting devices are attached by means of angle bars 22 and 2S bolted to the central part of the beam 1.

At 11 there is indicated by dotted lines the place of attachment and the relative position of the seat for the driver.

The central beam 1. is provided with plow disk 12 and suitably vconnecting devices for securing the disk to the inclined part 1S of the beam. The disk itself and also the 'means for securing itin position may be of any of the well known sorts. I employ connecting devices of such nature that the disk can be adjusted to either of several positions to permit it to stand inclined to the horizontal, and inclined both to the vertical transverse planes and the vertical lmigitudinal planes of the machine. be combined a scraping mechanism, as conventionally indicated at 20, of any preferred sort.

When it is desired to provide a two disk plow as indicated in Fig. 1 I employ a short supplemental disk beam indicated as a whole by 2, ithaving an inclined arm 1Q and an arm or plate 21 adapted to be bolted to the side of the forward arm 15 of the frame beam 1. At 13 there is a plow disk attached to this beam 2, which disk in practice has supporting, adjusting and cleaning devices similar` to those above described.

Tn Fig. 1 the front furrow wheel 6 and the land wheel 9 are not illustrated, but it will be kunderstood that use is made of supports and suitable means for attaching and adjusting them such as are conventionallj7 illustrated in Fig. 3.

When it is desired to provide a one disk lith the disk can plow the beam 2 and its disk 13 together with its attaching and adjusting devices are removed and the plow frame is set forward in relation to the draft beam 1, as shown. in Fig. 2, and is again rigidly fastened in place. When a plow with three disks is desired the rear easter furrow wheel S and the seat 1 1 are removed from the beam 1 and a second supplemental beam indicated. by .3 is attached to the part 1.7 as illustrated in Fig. b. This beam 3 has an outward inclined section 24 and. an oppositely turned section. 2 at the rear end. To the latter there is secured a plow disk 14 and with it there are combined fastening, adjusting and cleaning devices substantially similar to those above described. The rearfurrow wheel 8 and the seat 11 are also secured to this second supplemental `frame beam 3.

Upon comparison of the structures shown in Figs. 1, 2, 3, respectively, it will be seen that in each case the disk 12 and its frame bar 1 remain in substantially the same position along the central longitudinal lilies of the machine. This frame bar 1 and the draft frame or bar et constitute the governing element in the draft part of the apparatus. This disk 12 is under all adjustments substantially central, longitudinally, el' the. apparatus, and when the disks 1.5 and 1-1V are presentthey are situated symmetrirailly in relation to the central longitudinal lilies. There being no hinge joints either between the parts 1 and 4 or between the part 1 and either of those at 2 and 3 extreme rigidity is assured throughout the whole structure.

In Figs. 4, 5 and 6 :l have shown more. in detail parts which can he used as a draft beam or frame, to which the central plow beam 1 can be secured. 151 is a top bar or plat e. secured at its rear end to the bracket piece 26, there being a branch har 27 extending from the under side of the bracket to the upper side of the bar LLa. The draft frame t can be connected to the doubletree at 5 by links 29 .represents one or more curved links also interposed between the beam or frame 4 and the doubletree, and serving as am ians for connecting the front end of the dral't rod 30 which extends back to the carrier of the front furrow wheel 6. The parts which support this wheel include a vertical pivot ol' the well known character around which the wheel can turn in corresjmmlence with the turning of the horses and the swinging of the doubletree around the axis at 31, such turning causing the turning of the wheel through the draft rod 30.
